There are three or two peaches outside the bamboo. Is the Spring River Plumbing Duck Prophet Double?

These two sentences are not dual. Duality is a rhetorical way to express opposite, similar or related meanings with two phrases or sentences with the same structure, equal number of words and symmetrical meaning. Duality requires nouns to nouns, verbs to verbs, adjectives to adjectives, and quantifiers to quantifiers. Content words and content words, function words and function words.

Analyze the part of speech of these two sentences:

Apart from bamboo (noun) (directional noun), peach blossom (noun) has three or two branches (nouns).

Spring (noun) River (noun) Water (noun) Warm (adjective) Duck (noun) Know first (adjective) verb.

It can be seen that the parts of speech of the two sentences are not relative, nor are they antithetical sentences.

From the analysis of sentence structure, because the parts of speech are not relative, the structure of two sentences can not be the same.

There are three or two peach branches outside the bamboo (noun subject) (quantifier as predicate).

Chunjiang plumbing (subject-predicate phrase as prepositional object) Duck (subject) knows first (adverbial) (predicate).

The two sentences before and after are different in structure and do not constitute a dual sentence. Su Shi's "Night Scene of Hui Chong Riverside" (one of the two) is a quatrain, which does not require duality. (Seven laws, five laws, the first sentence can be right or wrong, generally the first sentence is not even. )

Supplementary note: "Spring River Plumbing" is the prepositional object of the subject-predicate phrase of "knowledge" in the poem. [In the phrase: Chunjiang (positive phrase as subject) plumbing (subject-predicate phrase as predicate)]
